To a stirred solution of 4-fluorobenzotrifluoride (9.85 g) and 4-aminothiophenol (7.51 g) in DMSO (60 mL), cooled in an ice bath, was added in one portion potassium t-butoxide (6.73 g). The resulting mixture was stirred at 0° C. for 10 minutes, then at 60° C. overnight. After cooling, the mixture was poured into water (600 mL) and the resulting mixture extracted with ether (2×200 mL). The organic phase was washed with 2N sodium hydroxide (50 mL), then with water (50 mL). After drying (MgSO4), the solvent was evaporated to give a brown solid. Recrystallization from hexane gave the title aniline as a yellow solid, m.p. 97-99° C.
